previously mentioned nozzle bodies.

by such a nozzle to the glassware. Attempts to carry out such a proposal have met with serious diiflculties. Among such dimculties are those involved in keepingthe liquid of the fluid mixture or mist supplied to the nozzle sufliciently atomized and satisfactorily distributed to the streams or Jets of gaseous fluid passing to and through the jet holes or discharge openings of the nozzle. Much of the liquid supplied to the nozzle may gather on the inner surface of the nozzle body as a downwardly flowing film thereon. When the nozzle hasv a number of jet holes in the wall thereof, at least some of which are in line downstream with other jet holes, as is-usual, some of these jet holes may not receive their intended quota of liquid. The jet holes in the line of flow of the liquid film from other jet holes may have been robbed of their intended quotas of liquid by the action of the outgoing streams or jets oi gaseous fluid at and adjacent to the up-stream jet holes.

An object of the present invention is to provide for improved control of the distribution of the liquid of a supply mist to the individual jet holes inthe wall of a glassware cooling nozzle so as to assure that the individual jet holes will all receive their intended quotas'of the liquid component of the cooling flu d.

In one form of nozzle embodying the invention, a separate conduit is provided within the nozzle body having holes for discharging fine jets or spray of the liquid radially through the gaseous fluid conducting passage of the nozzle toward the final discharge jet holes in the wall of the nozzle body. In this species of the invention. the respective jet holes in the wall of the nozzle body may be said to be provided individually with sepa-'- rate quotas of the liquid, each such quota being atomized in passing to and through its jet hole by the air or other.gaseous fluid also supplied to that jet hole.

An illustrative embodiment of the invention as above referred to is shown in the accompanying drawings, in which:

Fig. 1 shows a nozzle having a separate internally located liquid supply tube for supplying individual quantities or quotas of liquid to the respective final discharge jet holes of the nozzle body, and

Fig. 2 is a horizontal section on line 4-4 of Fig. 1.

The nozzle body shown in Fig. l. designated 30, is closed at its lower end, as in the case of the This nozzle body has a series of jet holes 3! in the wall thereof. These jet holes are of. any suitable size or sizes and the total number and relative arrangement thereof may be varied as desired. The

internal space within the nozzle body, indicated.

at 32, is open at the upper end of the nozzle sov as to receive a supply of air under pressure or other suitable gaseous fluid.

The liquid component of the final cooling mixture that it is desired to use is conducted into and longitudinally of the air conducting space 32 of the nozzle body, as by a centrally located liquid conducting pipe 33. This pipe is supported withinthe nozzle body in any .suitable way and is supplied with liquid from any suitable source of supply. The pipe 33 is closed at its lower end, as indicated at 34, and provided with lateral jet. holes 35, which respectively are in approximately radial alignment with the final discharge jet holes 3|.

In the operation oi the form of device shownin Fig. l, a jet of liquid is squirted from each of the jet holes 35 toward the aligned final jet hole 3|. The air or other gaseous fluid passing through the space or internal passage 32 within the nozzle body 30 to the jet holes 3i will break up the jets of liquid from the holes 35 if the liquid discharge from these holes is not already sufllciently atomized and will carry along the atomized particles through the jet holes 3|. The jets finally discharging from the holes 3| thus will comprise air or gaseous fluid carrying in an atomized state the desired quotas or amount: of liquid.

The liquid supply tube may be located and formed otherwise than as shown in Figs. 1 and 2. It may be disposed against or close to the inner wall of the nozzle body 30 and provided with --outlet openings suitably located in relation to the means for supplying individual quotes 01 liquid to the final discharge openings may be varied in structural details and speciilc mode of operation from that shown in Figs. 1 and 2. In some instances, it may be feasible to provide a liquid supply tube with fewer liquid discharge openings than the final discharge openings in the wall of the nozzle body, one or more of such liquid sup. ply openings then serving to supply liquid to a plurality of the final discharge openings. The size or sizes of the liquid supply openings and/or of the final discharge openings may be varied according to individual preferences or service requirements as may the particular shape or shapes of such openings.

The invention is not limited to the details of the illustrative embodiment of the invention shown in the drawings and herein described as various changes therein and modifications thereof will readily occur to those skilled in the art.

I claim:

1. A nozzle of the character described for use in tempering hollow glass articles, said nozzle comprising an elongate hollow body closed at its free end and constructed and arranged at its opposite end for connection with a source of supply of air under pressure, said hollow body having a longitudinally extending series of spaced jet holes in the wall thereof, a tube of smaller diameter than said hollow body located within the latter so as to extend centrally thereof and constituting a conduit for liquid, said last-named tube being closed at its end adjacent to the closed end of said hollow body and being provided with a longitudinally extending series of spaced jet holes, each opening toward and approximately in radial alignment with one of said first-named jet holes.

2. A nozzle of the character described for use in tempering hollow glass articles, said nozzle comprising an elongate hollow body closed at one end and adapted at its opposite end for connection with a source of supply of a cooling fluid under pressure, said elongate hollow body having spaced jet holes in the wall thereof, and an inner tubular conduit for fluid extending within said elongate hollow 'body longitudinally thereof and provided with jet holes opening toward and approximately in radial alignment with said first named jet holes.
